Check out Mark Wethman’s new quant blog, Congenial Times. It’s been around for only a couple of weeks but in that time he’s posted a lot of interesting data/analysis on topics ranging from international politics to human biodiversity. His most recent post is on racial differences in educational attainment in Sweden.
The most interesting article to me has been the one on Amish IQ scores. He found data which showed the Amish to have above average reasoning and quantitative analysis skills.* Data like this is essential for anyone trying to understand the Flynn Effect or between-population differences on IQ scores.
*They scored lower on language tests, but according to Jason Malloy this was solely due to the tests not being in their native Pennsylvania Dutch.
